MAP AND SHADE PROTECTOR.

' PEGIFIC'ATION forming part of Letters Patent No. 455,473, dated July '7, 18 91.

Application filed October 11, 1890. Serial No. 367.779.' (N model.)

To all whom it may concern.-

Be it known that I, FREDERICK J. LEMM, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain .new and useful rotatable roller, and usually a hollow rotat-,

able roller having within it a spring which is wound as the shade, map, or other article is pulled off the'roller, thereby rotating such roller, such spring rewinding the anticle upon the roller when released; and the object of my invention is to obtain a protector adapted to be secured to the holder forming bearings within or upon which the roller rotates which shall cover so much of the shade, map, or other mounted article as is wound upon the roller and protect such portion thereof from dust, dirt, water, or other article tending to ,disfigure or injure it. a

In the drawings which illustrate and form a part of this specification, Figure 1 is an elevation of one of the rotatable roller-holders and that one thereof which is adapted to hold that end of the shade-roller from which the metal rod having a squared end projecting from the roller extends, with the roller indicated by dotted lines; Fig. 2, an elevation of the other of the rotatable roller-holders; Fig. 3, a perspective View of the holder illustrated in Fig. 1; Fig. 4, a perspective of the protector; Fig. 5, an elevation of the holder illustrated in Figs. 1 and 2 so far as the essential parts of such holders relating to my invention are concerned, with a foot or base placed thereon, so that it may be at--' tached to a vertical wall or cleat standing in a plane parallel with the plane in which the shade, map, or other article contained on the rotatable roller is in when unrolled therefrom. Fig. 6 is an elevation of the holder adapted'tobe placed at the other end of the rotatable roller and with the holder illustrated in Fig. 5. Fig. 7 is a perspective view of the base of the roller-holder illustrated in Figs. 5 and 6; and Fig. 8 is a sectional view of the rotatable roller, the article mounted thereon, and the protector.

' d is a groove,

- Like letters refer to the same part where such part is shown in more than one View.

A is the protector, and is composed of two parts A A The part A has the edges a a thereof turned over to form grooves, in which grooves the edges a a of part A adj ustably fit. The part A is made-with its outside diameter of about the same size as the inside diameter of part A, and the adjustability re ferred to consists in the sliding movement permitted of part A in part A, whereby the length of the protector A is changeable.

a is a hole in the top part of the protector near each end thereof. This hole a as sometimes constructed by me has two sizes thereto, one, and the larger, being lettered a and the other (1*. i

B is the rotatable roller, to which the shade,

.map, or other article '1) is secured.

B is the stick attached to the the shade, map, or other article.

D is a casting forming a holder for that end of the roller B from which projects the shaft 1), having a squared end. To the shaft 1). is secured the spring when a in the rotatable roller B.

D is a flange on holders D, D, E, and E, extending about three-quarters of the way around the periphery of the holder.

D is a projection or lug on flange D d is a pin projection, which maybe cast rigidly on the holders D D E E.

d is a slot in holders D D E E, respectively.

d is a rim partially surrounding in the ordinary manner the slot d. The squared end I) of the rotatable roller B fits in to this slot (1', and is thus held from rotating.

which may be placed in projection or lug 01 when desired.

d d are holes in holders D D, through which the screw, nail, orbrad securing the holder in position is passed.

outer end of E E are right and left holders, containing,

sp ring is used as. hereinbefore stated, the essential elements of my invent-ion which are contained in hold ers D D, and in addition thereto'having the base 6 and neck 6.

e e are slots in base 6. I

It will be observed that the lower edge 01 of the flange D is cut away from a point substantially underneath the center of the ICC rotatable roller to a point substantially horizontal therewith, and that the protector A extends from such edge (1" around on the flange D to the edge (1 thereof, and from thence extends outward a short distance farther. The stick 13 will be raised when the article mounted on the roller B is wound tightly thereon underneath this extending edge of the protector A, and will then, in combination with the protector A, shield the article mounted on the rotatable roller from dust or other material.

Then the protector A is being placed in position on the holders D D or E E, the flanges are placed in the ends of the parts A and A respectively, of the protector, and hole a is fitted over the projection D. here the hole a is composed of two parts, as a and a and the projection D is provided with the groove d the larger part a of hole a fits over the projection D and then by turning the pro tector A a slight distance the part a of the hole a is slid underneath the head formed by the groove (1 The pin d, where used, comes outside of the protector A when such protector is over the flange D Where the pin cl is employed, I do not find it necessary to have the groove d in projection D and where the groove d is used with the two-part hole a the pin cl is not required. I have, however,in one instanceusedboththe grooveandtwo-part hole andthe pin d. The purpose of the projection D and hole a and the pin d is to prevent disarrangement of the protector A in case the stick B comes in contact with it when the shade,

map, or other article is allowed to be rapidly rolled upon the roller B by the spring contained therein. The pin D fitting in hole a, holds the parts A and A of the protector A from sliding together and where the protector is composed of more than one part is a quite necessary element of the device.

\Vhere the length of the rotatable roller B is greater than the length of the protector A, with the parts A and A slid out as far as safety will permit, an additional part A -or A as preferred, or even more than one such additional part, may be combined with the parts A and A by sliding them together in parts, one

the manner described. The combination of additional parts, duplicates of the parts A A to increase the length of the protector A is, however, so obvious that in the claims hereof I shall refer only to a two-part protector.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. In a protector and holder for shades and other articles, holders adapted to be secured to a frame and to contain therein a rotatable roller, such holders having a flange thereon extending a portion of the way around, in combination with a protector composed of two of such parts having the edges thereof turned into grooves and the other of such parts adapted to slide longitudinally within the first-named part, with its edgesinclosed in the grooves, substantially as described.

2. In a protector for shades and other articles, holders adapted to be secured to afranie and to contain therein a rotatable roller, such holders having a flange thereon extending a portion of the way around, in combination with a protector adapted to fit at the ends thereof over the flanges on the holders, and

such protector having holes therein fitting over projections on as described.

3. In a protector for shades and other articles, holders adapted to be secured to a frame and to contain therein a rotatable roller, such holders having a flange thereon extending a portion of the way around, in combination with a protector composed of two parts, one of such parts having the edges thereof turned into grooves and the other of such parts adapted to slide longitudinally within the first-named part,with its edges inclosed within the grooves, the protector being adapted to fit at the ends thereof over the flanges on the holders and having holes fitting over projections on the holders, substantially as de scribed.

the holders, substantially FREDERICK J. LEMM. In presence of F. N. ATwooD, J12, CHARLES T. BROWN.
